Quick Change Chucks

The CB-NX series collet chuck is a low profile dead length design with a reduced diameter nose for maximum tool clearance. In this design the collet is coupled to the chuck body and remains stationary as the tapered seat moves forward when the chuck is actuated. This design keeps the collet in a fixed Z axis position during clamping and does not create a pull back effect on the bar stock or workpiece.

CB-NX Features

• Dead Length design produces no pull back on the workpiece• Reduced diameter nose and short overall length provides increased tool clearance and maximum utilization of the machine's Z axis• Radial adjusting screws to true-up the chuck• Lubricated-for-life design requires minimal maintenance• All components hardened and precision ground for highest accuracy and long life• Stop plates and stop housings can be mounted inside the chuck body for chucking applications requiring end stops or part ejectors

In the CB-ND series collet chuck, the collet is coupled to the chuck body and remains stationary as the tapered seat moves forward when the chuck is actuated. This design keeps the collet in a fixed Z axis position during clamping and does not create a pull back effect on the bar stock or workpiece.

In the CB-NB series collet chucks, the collet is coupled directly to the draw tube connector. As the draw tube is actuated, the collet is drawn into the tapered seat of the chuck body, efficiently translating draw tube force into maximum clamping force.

CB-NB Features

Pull Back design maximizes the efficiency of the clamping system by concentrating all forces in the direction of the spindle for highest accuracy and greatest overall rigidity

The CB-NDR is a new patented Dead Length design collet chuck to be used with servo stop bar loaders. The NDR chuck is actuated as the draw tube is pulled into the machine spindle. The collet is coupled to the chuck body and remains stationary as the tapered seat moves forward during clamping. This feature keeps the collet in a fixed Z axis position, and since the draw tube is moving into the spindle, the bar remains positioned against the servo stop.

CB-NDR Features

Pull to Close Dead Length design produces no pull back and will not push the bar off the servo stop

Radial adjusting screws

Lubricated-for-life design requires minimal maintenance

All components hardened and precision ground for highest accuracy and long life

The NS series is a reduced diameter Dead Length design for sub spindles. Similar to ND chucks, the collet is coupled directly to the chuck body and remains fixed as the chuck is actuated. NS chucks also include a provision for mounting stops and ejectors inside the chuck body.

CB-NS Features

Small OD for maximum tool clearance on sub spindles.

Dead Length design produces no pull back on the workpiece.

Lubricated-for-life design requires minimal maintenance.

All components hardened and precision ground for highest accuracy and long life.

Stop plates and stop housings can be mounted inside the chuck body for applications requiring end stops or ejectors

The NRB series is a pneumatic or hydraulically actuated self-contained Pull Back design for stationary applications. The collet is coupled to the built-in piston and is drawn into the tapered seat as the chuck is actuated. Part stops and ejectors can be mounted inside the chuck body.

CB-NRB Features

Self-contained design with built-in cylinder can be hydraulic or pneumatically operated

Pull Back design maximizes the efficiency of the clamping system by concentrating the chucking force in the direction of the machine table, in addition to drawing the workpiece against the part stop
